I think you are closer. Maybe the GOP needs to find a quick replacement for McNuts. We have to go to war with the army we have and right now it is rather thin.
You're asking the GOP to put its selection process in upheaval 3 months before the election, and right when a major military power is flexing its muscles? Isn't that what the DIMocrats are supposed to be considering? Why in heck would the GOP commit suicide like that?
I'm no partisan for McCain. You'll see on this forum I've stated I'll not vote for the man. But what you propose is political suicide. Militarily, McCain is the best that can be offered right now. Domestically and on the illegal-immigration issues he's a disaster. But this is one area he shines in.
I agree with the posters who've said this could be a blessing in disguise for the GOP this year. It's going to shine the light on Obama's inexperience and naivety like nothing else.
